The rules behind the numbers
How we
count.
Every number in the index follows the same math, applied to public advertised prices with a check date. Here is all of it.
The one number
The sorting column is the settled monthly cost: the recurring medication price, converted to a calendar month, plus every mandatory recurring fee. Memberships and program fees count always; optional extras never do, though the table names them. Promo prices, first-month discounts and coupon codes are excluded from the main number and live in the first-month column instead.
Billing cycles
Some clinics bill per 28 days or per 4-week supply — thirteen charges a year, not twelve. Those prices are multiplied by 30.44 divided by the days in the supply, which adds roughly nine percent, and the row says so plainly.
Floors and ladders
A price marked FLOOR is the lowest rung of a published dose ladder or an advertised as-low-as figure — real, but not what most people pay at settled doses. Floors never earn the word cheapest on this site without that badge.
Commitment tiers
The main number is always month-to-month. A cheaper price that requires prepaying six or twelve months appears as a second line with the term named, because comparing a locked year against a free month is not a comparison.
Per-vial offers
When a seller prices a vial but does not publish how long it lasts at their own protocol, no monthly number can honestly be computed. Those offers sit in their own section priced per vial. We never substitute our dosing assumptions into someone else's price.
Dates and disappearance
Every row carries the date its price was verified on the clinic's public page, and each harvest keeps an HTML snapshot. A price older than 45 days grays out. When a clinic stops advertising a price, the row moves to a no-longer-advertised section for one edition before leaving the table.
Money and placement
No clinic pays to appear, to rank or to stay. If a clinic becomes a referral partner, its button says Partner and pays a flat fee per completed assessment — a fee that cannot change a number or a position, because the numbers come from their public page and the order comes from arithmetic.
